Electric-heating assembly for clothing

Abstract

An electric-heating assembly adapted to be attached to an article of clothing including: a power supply module, a heating module, and an electric-conductive module. The electric-conductive module is electrically connected between the power supply module and heating module for transmitting electricity from the power supply module to the heating module. The electric-conductive module defining a first inlet terminal and a first outlet terminal is formed by fixing at least one pair of conductive wires on an elastic strip in a stretchable manner, and the conductive wires of the same pair respectively allowing electricity to flow in and out to form a closed circuit with other electrical elements are arranged together to be attached to the elastic strip simultaneously and extend in the same pattern. The electric-heating assembly is controlled by an operable controller to turn on or off.
